產品總覽

The LM4861M is a 1.1W Audio Amplifier with shutdown mode. This Boomer series audio power amplifier capable of delivering 1.1W of continuous average power to an 8R load with 1% THD+N using a 5V power supply. Boomer audio power amplifier designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since the LM4861 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. This amplifier features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable can be configured by external gain-setting resistors for differential gains of up to 10 without the use of external compensation components. Higher gains may be achieved with suitable compensation.
  • No output coupling capacitors, bootstrap capacitors or snubber circuits are necessary
  • Compatible with PC power supplies
  • Thermal shutdown protection circuitry
  • Unity-gain stable
  • External gain configuration capability
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
